#Fukushima I Nuke Plant: Why Are the Radiation Levels in Reactors 5 and 6 So High? Or Is There Some Data Mix-up?

(UPDATE 4/29/2011) It seems that atmc.jp has been presenting the temperatures of the Spent Fuel Pools of Reactors 5 and 6 as the dry well radiation levels for Reactors 5 and 6. It does seem like a data mix-up (or data link mix-up). I have notified the site (atmc.jp) of the mix-up.

--------------------------------------------------

I don't know where the site "atmc.jp" gets the data (I can't find them in Nuclear and Industrial Safety Agency's press release about the status of the plant and plant parameters), but I've noticed the radiation levels of the dry wells (of the Containment Vessels) in Reactors 5 and 6 have been high, according to atmc.jp, the site that automatically compiles the Fukushima I Nuke Plant accident-related data.

The radiation levels are actually higher than the more troubled Reactors 2 and 3. The Reactor 1's dry well radiation measurement stopped after the radiation registered 100 sieverts/hr on April 8.

As of April 29, Reactor 5's dry well radiation level is 40.3 sieverts/hr, and Reactor 6's dry well radiation level is 33.5 sieverts/hr.

In comparison, Reactor 2's dry well radiation level is 22.1 sieverts/hr, Reactor 3's 14.1 sieverts/hr.

Here are the numbers for the Reactor 5 dry well radiation, from atmc.jp:
